b40db42196 Use std::move rather than just move 
Apparently:

  "warning: unqualified call to 'std::move' [-Wunqualified-std-cast-call]"

is default in new XCode.

f278e7e312 feat: Add new tunable --shm-metadata-msg-size 
The shm metadata msg will be right-padded to the given size. This
tunable may be used to saturate the kernel msg buffers more quickly with
the effect that the ZeroMQ message queue size - on which the FairMQ
shmem transport relies upon - behaves more accurately for very small
queue sizes.

This introduces a change for the meta msg format in the multipart case:
old: | MetaHeader 1 | ... | MetaHeader n |
new: | n | MetaHeader 1 | ... | MetaHeader n | padded to fMetadataMsgSize |
where `n` is a `size_t` and contains the number of following meta headers.
Previously, this number was infered from the msg buffer size itself which is
no longer possible due to the potential padding.

Implements #432

2e98a4e2cb feat(ofi)!: Remove ofi transport 
BREAKING CHANGE

Due to a lack of users, we remove the experimental code. The
latest implementation can be found in release v1.4.56. This does
not mean it will never be picked up again, but for now there are
no plans.
